JOHN H. DALE-03F NEW YURK, NIY.

2T0 all wkomsit may concern:

szen of the United States, residing at the city of .New York, inthe:borough.of Manhattan -andiState of'New York, have invented certain:new and us.eful Improvements in Elec- -";'.tr' i'c-Lighting Fixtures,of which the follow in is a full, cleansandexactdescription.

r This invention relates to electric lighting systems and has specialreference to that style of lighting fixture which is used in indirectlightingsystems.

The object of the invention .is to provide afixtureofthis class whichwill, to the-least extent,:obstruct theraysof light which are projectedupward toward :the ceiling from the slampsthat areattac'hed to thefixture.

Another obj ect of the invention isto -.pro-

videin asimple and compact fixture means -for usingfpull-sockets, and. astill further ob- 1j ect of the invention is ito provide. a fixtureof'thisclasszinuwhich theshade can be read- .ily zremoved and .replacedfor cleaningpurposes by a simple operation and without disturbing thelamps.

"With these and other objects in view, the

- general construction ofmy improved fixture comprises the combinationof a=hollow hub and a shade supporting .pan detachably secured-.thereto,=thehub and pan being connected :tO-ihe center or lowermostpoint of the shadeand. being adapted to support .the lamps intan:upwardly and outwardly inclined position, and to accommodate the.pull-c'hains Oft'll8.-S0Ok9ilS ofsaid lamps by i pel'mittingtthem topass :through the hub anditheapan for convenient manipulation at-apointbelow-the shade. The'hub and pan are supported at the lower endof ai'tubular stem, whichstem is the only part of the fix-;tureinterposed betweenthe lampsand the ceiling.

My invention also includes other details and constructions which will befullyhereinafter described and particularly-pointedout in the claims.

leads through the neck 6 and affords free communication-tothe interiorof thehub '1.

'The upwardlyextending sides 8 ofthe pan 2 'lucent, making the fixturesemi-indirect.

In any case the central or-lowest point of the shade is provided with anopening which may or may not be surrounded by a flange or neck 10.Shades of this character are usually provided with such a flange forwhich reason it is shown inthedra'wing. These openings or flanges are ofdifferent stock sizes and my fixture is designed to receive and supportshades which have any of the The shade isadjusted to the fixture byfirst unscrewing the pan 2 'from the hubl and then placing the shade inthe position shown in Figs. 1 or 3 so that its inner surface willrestagainst the under wall of the hub and sub- The pain is then screwed intothe hub until its bottom. or side flange 8 comes in contact with theexterior of the shade. The external diameter of the boss 5 issuch thatthe shade having the smallestopening will neatly fit around it while theinternal diameter of the side flange 8 of the pan is such that theflange 10 of a shade having the large size of opening will neatly fitinto it. Whena shade having openings of either ofthese two sizesisused,it will bemaintained firmly in a concentric position either bythe boss 5 or the v to the fixture, such, for instance, as shown in ingof an intermediate size is to be'adjusted Fig.1, 1 use a spacing ring.or collar 11 which rests freely in the pan 2 and which fills thespacebetween the external surface of the boss 5 andthe internalsurface'of the flange 10 and thereby centers and maintains the positionof the shade.

Fig. 3'shows a shade havingthe' smallest size of 'openingan'd, asdescribed, -is c,entered by direct contact with the boss 5. It will beseen that when the shade is attached to the fixture in the mannerdescribed it is held firmly between the pan and the hub in a perfectlyconcentric position; it is held in place without screws and the onlypart .of the fixture necessary to remove in order to remove the shadefor cleanlng purposes,

is thepan 2 which can be readily and quickly unscrewed. This method ofsupporting the shade I believe to be novel in indirect lighting systemswhere the usual practice is to attach the upper edge of the shade eitherto a spider extending from the central stem or by means of chains orrods leading upward from the outer edge of the shade. All suchcontrivances are objectionable because they obscure the light from thelamps which are inclosed withinthe shade.

The lamps 12, any suitable number of which may be used, are supporteddirectly by the hub 1 from the upper wall of which they radiate in anoutwardly and upwardly inclined position. Being thus disposed no part ofthe fixture except the central stem 4 is located between the lamps andthe ceiling, not even the sockets 13 of the lamps themselves are abovethe lamps, the result of which is that the full benefit of thecandlepower of the lamps is obtained for illuminating purposes andshadows and spots are avoided. The lamp sockets are sustained by meansof the usual threaded nipples 14 fixed in the upper wall of the hub 1and adjacent to each nipple a perforation 15 through the Wall of the hubis provided through which to 0. ss thechains 16, when pull-sockets areused, for controlling the respective lamps. These chains after passingthrough the perforations .15, lead through the interior of the hub 1 andthepassage 7 in the pan to a suitable pointbelow the fixture in aconvenient position to be reached and manipulated. All of the chainsthus lead through one central opening and become less conspicuous thanif they were widely separated or extended over the upper edge of theshade, as is often done.

The hollow hub 1 also has the additional function of housing the wiringof the fixture. The two main wires 17 and 18 lead chains leading fromthe sockets inside of are spliced to branch wires 19 and 20, one

pair leading to each of the lamps and passing thereto through thenipples 1 1. This wiring is shown conventionally in Fig. 1.-' but inpractice it will be understood that the wires being heavily insulatedand having taped joints, willoccupy considerable of the space within thehub. They can, however, be so packed into the hub as to leave sufiicientspace for the pull-chains to pass through.

While I have referred herein to the part 1 specifically as the hub andthe part 2 as a pan attached thereto, it is to be understood that thishub and pan when taken together constitute a single hub or hub-likestructure, which engages with the central point of an upwardly extendingshade and from which the lamps radiate upwardly and outwardly and thatthis hub constitutes a housing for the wires and 'afi'ords a passage forthe the shade to the exterior thereof.

\Vhat I claim is:

1. An indirect electric lighting fixture comprising a shade, a hubdetachably connected therewith at its central portion, lamps supportedby said hub, said hub being provided with a central passage andpull-chains for controlling said lamps and leading through said passage.

2. An indirect electric lighting system comprising a two-part hub, themembers of which are detachably secured together, one ofsaid parts beingadapted to support a' shade and the other part being hollow andsupporting lamps, the wiring of said lamps being housed within the saidhollow part.

said hub being provided with openings and pull chains leadingthroughsaid openings.

3. An indirect electric lighting fixture comprising-a hub having apassage therethrough; a plurality of pull-sockets at tached to said hub,pull-chains extending from said sockets through the passage of saig. huband a shade mounted upon said hu 1. In an electric light fixture thecombination of a shade having a central opening; a pan adapted tosupport said shade, said pan having a central neck and a peripheralflange, and a spacing ring inserted between the edge of the opening inthe shade and the central neck of the pan for the purpose set forth.

In witness whereof I subscribe my signature, in the presence of twowitnesses.
